Current Status
On the accelerator side:
--> Beam was delivered into the hall overnight.
--> Raster size was far too large (like 10x10 mm) for the requested 3x3 mm. This caused significant confusion overnight.
On the Hall side:
--> Started beam check out late swing/owl but were confused by raster.
--> Raster size could not be verified so Moller measurement was started.
--> Concluded that raster was very large and using the carbon hole empirically set the size of the raster.
--> Beam check out was completed and detector check out is ongoing.
